PENBERTHY SERIES N2/K2 TUBULAR GAGECOCKS

InstallatIon, operatIon and maIntenance InstructIons

2 INTRODUCTION

Penberthy tubular gagecocks are used to

isolate tubular glass or other apparatus from

the holding or pressure vessel when it becomes

necessary to drain and service the tubular gage.

Penberthy Series N2 and K2 gagecocks are

supplied in pairs, (upper and lower), that house

each end of a transparent sight glass tube and

are available with socketweld, flanged or NPT

connections. This gagecock/glass combination

forms a gage that accurately indicates fluid

level as well as fluid characteristics. These

gagecocks are equipped, as a standard feature,

with a union vessel connection and ball check

shut-offs to prevent leakage of contained fluid in

case of accidental tubular glass breakage.

Series N2 and K2 gagecocks for process use

should include a ball check shut-off feature.

Gagecocks without the ball check shut-off

feature will not stop leakage of contained fluid

automatically in the event of accidental tubular

glass breakage.

2.1 System description

Penberthy tubular gagecocks comprise six

basic components. Each component may vary

slightly, depending on the desired physical

and mechanical properties for the gagecock.

Use the exploded parts view in Section 11 as

additional reference material.

Body - a pressure retaining structure through

which fluid passes to enter a tubular glass or

other apparatus. Provides a rigid, union, or

spherical union connection to the vessel and

seating surfaces for most gagecock components.

Series N2 and K2 are offset pattern bodies.

Ball checks - sphere installed loosely within

the body of the gagecock that seats to prevent

significant leakage when a differential pressure

surge occurs (e.g., mechanical failure). Ball

checks for ASME steam service incorporate a

vertically rising lower and leaky horizontal upper

or omit ball checks completely. 'Reverse acting'

ball checks are available for vacuum service.

Trim - wetted parts that mechanically control

the fluid path from the vessel to the tubular

glass or other apparatus. The ball and stem

act to seal and release the fluid. In the event of

mechanical failure, the ball will seat to prevent

large quantities of the contained fluid from

exiting the vessel. Fluid is allowed to exit the

vessel into the tubular glass or other apparatus

when the stem is screwed away from its seated

position. The fluid is sealed when the stem is

screwed into its seated position.

The stem packing retainer provides a

compression surface between the process fluid

and the stem packing. A stem packing gland

is used to compress the packing against the

retainer and around the stem to prevent leakage.

Stem packing- under compression, the stem

packing is forced to mold around the stem and

prevent leakage of fluid during operation.

Gage connection - provides connection between

the gagecock and the tubular glass or other

apparatus. A stuffing box style which allows for

the glass packing to be forced to mold around

the tubular glass and prevent leakage of fluid

during operation.

Handwheel/lever - rotated to engage threads

and provide screw action of stem.

WARNING

Vessel fluids may be pressurized and can exit

vessel connections unexpectedly due to apparatus

or material failure. Safety glasses should be worn

when installing a gagecock. Failure to follow any

instruction could possibly result in a malfunction

of the gagecock with resulting sudden release

of pressure, severe physical injury or property

damage.

Safety instructions

Emerson does not have any control over the

manner in which its gagecocks are handled,

installed or used. Penberthy cannot and will

not guarantee that a gagecock is suitable or

compatible for the user's specific application.

WARNING

NEVER exceed these design ratings or application

data. Exceeding design ratings or

application data may result in mechanical failure

of gagecock components resulting in serious

personal injury or property damage.

3.2 Steam application

Penberthy series N2 and K2 gagecocks are

designed for process conditions. In low pressure

steam/water applications (< 350 psig [2410 kPa]

at 434°F [223°C], the use of N2 and K2 series

gagecocks is allowed because the potential

mechanical stress imposed on the gagecock

assembly by the thermodynamic steam

environment is relatively small.

5 INSTALLATION

Installation should only be undertaken by

qualified personnel who are familiar with

this equipment. They should have read and

understood all of the instructions in this manual.

The user should refer to relevant technical

data sheets or the product proposal to obtain

dimensional information for specific size and

model gagecock set.

Recommendations on tubular gagecock

installations are limited to the installation of

tubular glass liquid level gages when used as

liquid level indicating devices. The number of

different types of gagecock installations is too

great to explain adequately in an installation

manual. Therefore, it is the user's responsibility

to assure that knowledgeable installation

personnel plan and carry out the installation in a

safe manner. The following procedures are some

of the guidelines that should be employed.

5.1 Mounting

1. Prior to installation, turn the handwheel or

lever of each gagecock clockwise until the

stem closes against the seat.

2. Remove union vessel connections from

gagecocks, where applicable, and apply heavy

grease (where allowable) to tailpipe seat. (The

grease minimizes galling of the seat surfaces

when tightening the coupling nuts).

3. Wrench tighten tailpipes of upper and lower

gagecocks to the vessel using PTFE tape, or

equivalent, on all male tapered pipe thread

connections as shown in Figure 1. Make sure

the coupling nuts are in place on the tailpipes

prior to assembling to vessel. If the gagecock

is flanged or weld mount, use proper industry

standard procedures.

4. Mount upper and lower gagecocks to vessel

tailpipes making certain that tubular glass

connections are aligned vertically and to

vessel centers as called for on application

specification. Union vessel connection should

only be snug at this time.

4 INSPECTION

On receipt of a gagecock set, check all

components carefully for damage incurred in

shipping. If damage is evident or suspected,

do not attempt any installation. Notify carrier

immediately and request damage inspection.

Refer to exploded view drawing in Section 11 to

inventory parts.

4.1 User rating inspection

The user should confirm that:

1. The gagecock set model number and

pressure/temperature rating stamped on

nameplate conforms to the description on

the user's purchase order

2. The operating conditions described in

the purchase order agree with the actual

operating conditions at the installation site

The actual operating conditions at the

installation site are within the application data

shown on the relevant technical data sheet or

product proposal referred to previously

4. The materials of construction of the

gagecock set are compatible with both

the contained fluid and the surrounding

atmosphere in the specific application.

Safety instructions

If the size, model or performance data of the

gagecock set as received does not conform with

any of the criteria above, do not proceed with

installation. Contact an authorized Penberthy

distributor for assistance.

5.2 Tubular glass installation

1. Turn upper gagecock counterclockwise

(approx. ⅛ turn).

2. Loosen glass packing nut to insure there is

no compressive force on glass packing.

3. Insert tubular glass up into upper gagecock

stuffing box connection.

4. Return upper gagecock to its original

position while holding tubular glass in place

with upward force to insure its clearing

of lower stuffing box connection. Check

vertical alignment of gagecocks.

5. Loosen glass packing nut on lower

gagecock and pull glass down into lower

gagecock stuffing box connection to a

positive stop.

Tighten upper and lower vessel coupling nuts.

7. Tighten upper and lower glass packing nuts.

Note: in some circumstances, it may be

necessary to remove glass packing nut, glass

packing gland and glass packing and mount

them on tubular glass prior to insertion of glass

into upper and lower gagecock bodies. See

Figure 2 for proper assembly sequence.

6 OPERATION

Before initializing gagecock operation, check

that all installation procedures have been

completed. Use only qualified, experienced

personnel who are familiar with tubular

gagecock equipment and thoroughly

understand the implications of the tables and

all the instructions. Check to determine that all

connections are pressure tight.

WARNING

Gagecock installations should be brought

into service slowly. The tubular glass used

in gagecocks is tempered and can withstand

minimal thermal shock and mechanical stress.

Gagecocks should be opened slightly, and the

gagecock assembly temperature and pressure

allowed to slowly equalize. If the gagecocks are

equipped with ball checks, the gagecocks must

be opened all the way after the pressure and

temperature have equalized to permit operation

of the automatic ball check in the event of tubular

glass failure. Failure to follow the recommended

operating procedures can result in severe

personal injury or property damage.

6.1 Hydrostatic test

Take all precautions necessary to handle

the possibility of leakage during the test.

Hydrostatic pressure test all installations to

100psig (690 kPa) and correct any leakage

before proceeding.

7 MAINTENANCE

WARNING

Use only qualified, experienced personnel who

are familiar with tubular gagecock equipment

and thoroughly understand the implications of the

tables and all the instructions. DO NOT proceed

with any maintenance unless the gagecock

assembly has been relieved of all pressure or

vacuum, has been allowed to reach ambient

temperature and has been drained or purged

of all fluids. Failure to do so can cause serious

personal injury and property damage.

The user must create maintenance schedules,

safety manuals and inspection details for each

gagecock. These will be based upon the users

own operating experience with their specific

application. Realistic maintenance schedules

can only be determined with full knowledge of

the services and application situations involved.

During system shutdown, the gagecocks should

be left open to permit the tubular glass to lose

pressure and cool with the rest of the system.

Failure to leave the gagecocks open during

system shutdown may trap high-pressure fluid

in the tubular glass.

7.1 Preventative maintenance

On all installations the following items should

be evaluated regularly by the user for purposes

of maintenance:

1. Leakage around stem area

2. Internal stem leak

3. Leakage around stuffing box connection

4. Internal or external corrosion

The user must determine an appropriate

maintenance schedule necessary for his or her

own specific application, upon evaluation of

his or her own operating experience. Realistic

maintenance schedules can only be determined

with full knowledge of the services and

application situation involved.

7.2 Ball check shut-off

Safety instructions

Ball checks, when installed, may fail to seat

due to corrosion of the ball or seat, foreign or

viscous material in the ball chamber. A routine

operational test of the ball check can prevent

significant seepage of fluid in the event of

tubular glass breakage.

An operational check can be performed on the

gagecock ball check by closing both the upper

and lower gagecock stems completely. Drain

contents from and relieve pressure on tubular

glass to an appropriate safe container/area.

Note: some loss of process fluid to the drain

line is expected with this test procedure.

WARNING

Use only qualified, experienced personnel who

are familiar with tubular gagecock equipment

and thoroughly understand the implications of the

tables and all the instructions. DO NOT proceed

with any maintenance unless the gagecock

assembly has been relieved of all pressure or

vacuum, has been allowed to reach ambient

temperature, and has been drained or purged

of all fluids. Failure to do so can cause serious

personal injury and property damage.

With drain line in place, open BOTTOM gagecock

as rapidly as possible. Listen for 'click' sound,

which will indicate that the ball has seated. If

possible, observe the quantity of flow from the

drain line. Flow should either stop completely

or be no greater than single drips (no solid

stream). Close lower gagecock. Repeat above

procedure for UPPER gagecock. There must be

a pressure differential of at least 5 psig (35 kPa)

for the above procedure to work properly.

If the above procedure is not successful,

the only alternative is to isolate the tubular

gagecock assembly from the vessel or to shut

the process down completely. Disassemble

the gagecock as outlined in section 8.1 using

the exploded parts drawing in Section 11 as a

reference.

Visibly inspect ball check and ball seats in the

gagecock body. Remove any foreign matter and/

or replace with new ball checks if inspection

indicates this is required. If the ball seat is

damaged, consider replacing the gagecock

or the seat (if it is removable). Reassemble

gagecocks as outlined in Section 8.2.

7.3 Troubleshooting

Stem packing leakage - can often be

stopped by tightening the stem packing nut.

If leak persists, the stem packing should be

replaced by following steps 1) through 4)

of the Disassembly and 1) through 7) of the

Reassembly instructions

Internal seat leakage - is an indication of a worn

or damaged stem or seat. To replace the stem

follow steps 1) through 4) of the Disassembly and

1) through 7) of the Reassembly instructions. To

renew the seat surface (Series N2), follow steps1)

through 3) of the Disassembly instructions.

Renew the seats by using a fine lapping

compound and a mandrel the same size, shape

and seat angle as the stem. Flush the gagecock

body clean and reassemble by following steps 4)

through 7) of the Reassembly instructions.

Renewable threaded seats (Series K2). Remove

the seat by inserting a ¼" (6 mm) square driver

in the seat and turning it counterclockwise.

Install the new seat by turning it clockwise

using the square driver, making sure that the

ball check, if used, is replaced in the body.

Tighten the seat in place.

Leakage around union connections - can often

be stopped by tightening the union coupling

nut or remake connection using PTFE tape, or

equivalent, on all male pipe threads as shown

in Figure 1.

Leakage around stuffing box connection - is an

indication of worn out glass packing or improper

compression of glass packing. To replace

glass packing, follow steps 7) through13)

of the Disassembly and 8) through 16) of

the Reassembly instructions. In the event of

improper packing compression, leakage can be

stopped by tightening the glass packing nut.

Internal or external corrosion - could be an

indication of a misapplication. An investigation

should be carried out immediately to

determine the cause of the problem. It is the

user's responsibility to choose a material of

construction compatible with both the contained

fluid and the surrounding atmosphere.

Broken tubular glass - replacement, follow

steps 7) through 12) of the Disassembly and

10)through 16) of the Reassembly instructions.

8 REMOVAL - DISASSEMBLY - REASSEMBLY
